May I please have help for my SRP?

I have a school SRP and my question is how the wavelength of light affects the growth (height) of plants. I'm using cellophane as a light filter and watercress as my plant as it will be easier for me to measure height.
However, my school wants us to have both our independent and dependant variables be quantitative. However, I'm uncertain whether the wavelength would be considered quantitative as I'm only using 6 wavelengths (for the 6 colours) and a white light one (without cellophane). As I'm only using 6 specific wavelengths, this means it isn't continuous and I wasn't sure whether it would still be considered as quantitative because it seems more like discrete. Due to this, I also don't know what graph to use either. I was thinking of using scatter graph, but I'm picking 6 specific wavelengths so I wasn't sure if it's correct.
I'm also using white light as a control which is no cellophane. However, white light is a combination of wavelengths. We have to graph our results up, and I'm not sure how to graph up white light since it's multiple wavelengths. I was originally going to use a column graph so I could just say that it is white light, but my school wants it to be quantitative for the independent variable so I have to include the wavelength and I'm not sure how to do it.
I'm so sorry if this is confusing. I would be happy to provide further clarification if I didn't make sense for something. I just really need help.
Any help would be appreciated!
Thanks!
